Thirteen-year-old Kyle thought spending a vacation on the Oregon coast with his family would be great. He'd never flown before, and he'd never seen the Pacific Ocean. But Kyle's perfect vacation becomes a nightmare while he's babysitting his sister, BeeBee. An earthquake hits the coast and starts a fire in their hotel. While fighting their way through the smoke and flame, Kyle remembers seeing a sign at the beach that said after an earthquake everyone should go uphill and inland, as far from the ocean as possible. Tsunamis, giant waves that often follow earthquakes, can ride in from the sea and engulf anyone who doesn't escape fast enough. Can Kyle and BeeBee outwit and outrun nature's fury to save themselves from tsunami terror?
